claude-agent-radar 0.1.1

AI Agent capability boundary diagnostic — scan Claude Code filesystem fingerprints into six-dimension maturity scores.

agent-radar · AI Agent Capability Boundary Diagnostic

Detects the capability boundary of how an individual or a team uses the Claude Code ecosystem. It scans filesystem fingerprints and quantifies a person's mastery of CLAUDE.md, skills, MCP, hooks, subagents, and so on into six dimensions of maturity score (0–100), then outputs an HTML radar-chart report.

Two-layer measurement:

• agent-radar scan measures configuration completeness (static fingerprints, six config dimensions)
• agent-radar session reads local ~/.claude/projects/*.jsonl to measure actual usage (which tools, Skills, MCP servers actually fire, plus user correction rate)

The gap between the two is the most concrete improvement checklist. The repo itself is also a Claude Code skill (see SKILL.md) — drop it into ~/.claude/skills/agent-radar/ and it works out of the box.

Core Idea

How well someone uses Claude Code gets imprinted into their filesystem and session logs. This tool reads those fingerprints rather than monitoring conversation content.

• Configuration completeness (static) reflects how much you've written down: CLAUDE.md, skills, MCP.
• Actual usage (dynamic) reflects whether those configs actually fire during sessions.

Plenty of people write a thorough CLAUDE.md and install five MCP servers, but nothing in those configs gets exercised during real sessions. That gap is exactly what agent-radar visualizes — two overlaid radar polygons make it obvious.

Six Config Dimensions (agent-radar scan)

Dimension	What it detects
CLAUDE.md maturity	Presence, user/project layering, structured sections, imperative tone, concision, @import modularization, size lint
Skills usage	Whether skills exist, SKILL.md description trigger quality, progressive disclosure, frontmatter & token-hygiene lint
MCP integration	Number of MCP servers and breadth of types (data / saas / cloud / search / files)
Automation	hooks, subagents, custom slash commands, plugins
Context hygiene	user/project settings separation, shared vs. personal config distinction (gitignore), modular references
Iteration & maintenance	Whether configs have been repeatedly tuned over time (via git history)

Lint signals are borrowed from felixgeelhaar/cclint and the agentskills.io Skill Linter (required frontmatter fields, line-count limits, ASCII-art / decorative-content detection, oversized-CLAUDE.md warnings). They are reimplemented in pure Python — no external dependencies.

The total score maps onto five levels: L0 (unaware) → L4 (mastery).

Six Usage Dimensions (agent-radar session)

Dimension	What it measures
tool_diversity	How many distinct tools have been called in the session
skill_triggered	How many times the Skill tool actually fired (signal that skill descriptions trigger)
mcp_triggered	How many mcp__* tool calls happened (signal that MCP is really used)
low_correction	Rate of corrective user messages (inverted — lower is better)
context_efficiency	Rate of repeated reads of the same file in one session (inverted)
session_volume	Session count and message volume (exposure baseline)

Install

Prerequisites: Python 3.8+ (standard library only — zero external deps).

Option A · Install from PyPI (recommended)

The PyPI distribution name is claude-agent-radar (PyPI rejected the shorter agent-radar because of a name collision with an unrelated package). The CLI command and module are still agent-radar and agent_radar respectively.

The two recommended install methods put agent-radar.exe on your PATH automatically — no manual edits needed.

# Recommended · pipx (works out-of-the-box on every OS)
pipx install claude-agent-radar

# Recommended · uv tool (if you already use uv)
uv tool install claude-agent-radar

# Inside an activated virtualenv
python -m venv .venv
.venv\Scripts\activate           # Windows
source .venv/bin/activate        # macOS / Linux
pip install claude-agent-radar

# Editable install while hacking on the source
git clone https://github.com/millerlai/agent-radar
cd agent-radar
pip install -e .

After install, verify:

agent-radar --help

If pipx / uv tool install succeeded but agent-radar is still command not found, your shell hasn't picked up the tool-bin dir yet — run pipx ensurepath or uv tool update-shell, then reopen the shell.

⚠️ Avoid pip install --user claude-agent-radar on Windows. The executable lands in %APPDATA%\Python\Python3XX\Scripts\, which is not on PATH by default, so agent-radar will print command not found immediately after install. Use pipx instead.

If for any reason the CLI isn't on PATH, python -m agent_radar is a drop-in replacement (same arguments):

python -m agent_radar --help
python -m agent_radar scan ...     # same args as `agent-radar scan ...`

Option B · Install as a Claude Code skill (recommended for daily use)

The repo itself is a Claude Code skill (the root contains SKILL.md). Copy it into your user-space skills directory:

# macOS / Linux / Cygwin
cp -r /path/to/agent-radar ~/.claude/skills/agent-radar

# Windows PowerShell
Copy-Item -Recurse C:\path\to\agent-radar $env:USERPROFILE\.claude\skills\agent-radar

After that, in any Claude Code session, just say something like the following — Claude will load the skill and walk you through the scan:

• "audit my Claude Code maturity"
• "scan this repo's Claude Code setup"
• "find the blind spots in my agent config"
• "benchmark our team's Claude Code adoption"

The skill invokes the same agent-radar CLI, so the package must be installed first (pipx install claude-agent-radar is the path of least resistance), or you must launch it via python -m agent_radar from inside the skill directory.

Run

30-second quick start

Scan the current repo + your user-space, generate the full HTML report including the actual-usage radar. Run from the repo you want to scan:

agent-radar scan --include-home . -o scan.json
agent-radar session -o session.json
agent-radar report scan.json --session session.json -o report.html

# Open the report
open report.html        # macOS
xdg-open report.html    # Linux
start report.html       # Windows (PowerShell / cmd)

If agent-radar is not found, swap every agent-radar for python -m agent_radar (same arguments). See the install notes above.

Subcommands

Subcommand	Purpose
agent-radar scan	Scan filesystem fingerprints (six config dimensions)
agent-radar session	Scan local ~/.claude/projects/*.jsonl for actual-usage metrics
agent-radar report	Build single-file HTML radar report
agent-radar usage	Score OTel events into usage.json
agent-radar merge	Merge scan.json + usage.json into merged.json

Each subcommand has its own --help. Long form: python -m agent_radar <sub> ....

Three scan scenarios

Scenario 1 · Single repo (simplest)

agent-radar scan /path/to/repo -o scan.json
agent-radar report scan.json -o report.html

Scenario 2 · Personal full-body scan (includes user-space)

Pulls ~/.claude/ into the scan so you can see user-level vs project-level config separation:

agent-radar scan --include-home /path/to/repo -o scan.json
agent-radar report scan.json -o report.html

Scenario 3 · Team benchmark (multi-repo)

Scan many repos at once. The report auto-generates a ranking table:

agent-radar scan /repos/a /repos/b /repos/c -o scan.json
agent-radar report scan.json -o report.html

Add actual-usage measurement (full two-layer analysis)

agent-radar session reads local ~/.claude/projects/*.jsonl and emits usage metrics — actual tool invocations, Skill firings, MCP calls, and user-correction rate. Pair it with agent-radar report --session to get a second radar in the HTML:

# 1. Scan all projects (defaults to ~/.claude/projects/)
agent-radar session -o session.json

# Or restrict to specific repos
agent-radar session /path/to/repo -o session.json

# 2. Cygwin / cross-OS: point at the actual projects dir
agent-radar session --projects-dir /c/Users/<you>/.claude/projects -o session.json

# 3. Build the two-layer radar report
agent-radar report scan.json --session session.json -o report.html

Output files

File	Produced by	Contents
scan.json	agent-radar scan	Config completeness: six dimension scores + per-signal detail
session.json	agent-radar session	Actual usage: per-project tool calls, Skill / MCP triggers, correction rate

Limitations

• Only effective for targets you have filesystem access to (your own / your team's repos).
• For strangers with only code or a conversation, reliable detection is impossible, and it edges into the gray area of surveilling others — not recommended.
• agent-radar session only reads local JSONL; cross-machine measurement needs OpenTelemetry (agent-radar usage).
• Correction rate is matched on literal patterns (no/don't/stop/不對/還原…); semantic corrections (a long explanation of why Claude was wrong) are not detected.
• The scoring weights are tunable heuristics — calibrate them against your team's reality before doing cross-person comparisons.
